A polar region is any geographic area within the Arctic or Antarctic Circles, roughly above 66.5° latitude north or below 66.5° latitude south, characterized by extreme seasonal light variation, sub-zero temperatures for much of the year, and unique solar irradiance patterns. In solar technology, this definition matters because these zones present distinct challenges and opportunities that fundamentally change how photovoltaic systems are designed, installed, and operated.
